Here is a patch to bring both libpq and psql to a state where it compiles on
win32 (native) again. A lot of things have changed, and I have not been able
to keep up with them all, so it has been broken for quite a while.
After this patch, at least it compiles. It also talks "basic talk" to the
server, but I have not yet tested all things. Sending queries, and using
e.g. \d or \dt works fine. The rest will have to be tested further.
It also bumps the version on libpq.dll to 7.0.

Everything should be enclosed in #ifdef WIN32, unless I have missed
something. Except for one or maybe two places where I have moved a #include
that should not be used on win32 from the "global area" into a "#ifndef
WIN32 area".

Attached is a patch which patches cleanly against the Sunday afternoon
snapshot. It modifies pg_dump to dump COMMENT ON statements for
user-definable descriptions. In addition, it also modifies comment.c so
that the operator behavior is as Peter E. would like: a comment on an
operator is applied to the underlying function.

Thanks,

Mike Mascari

Also, get rid of numeric's private allocation freelist, which is no longer
a win since Jan rewrote palloc.

coerce_type, so that the right things happen when coercing a previously-

Of the standard types, only 'timestamp' seems not to have an array type;
should it be added, or are we going to remove that type for 7.0 anyway?

now truncate or pad to the specified length.

SQL cast constructs can be performed during expression transformation
instead of during parsing.  This allows constructs like x::numeric(9,2)
and x::int2::float8 to behave as one would expect.

read is reused for successive attributes, instead of being deleted and
recreated from scratch for each value read in.  This reduces palloc/pfree
overhead a lot.  COPY IN still seems to be noticeably slower than it was
in 6.5 --- we need to figure out why.  This change takes care of the only
major performance loss I can see in copy.c itself, so the performance
problem is at a lower level somewhere.

by creating a race condition.  It wasn't waiting for select() to say

an unhelpful 'broken pipe' error message if connect failed, rather than
the intended error message.
